IMPROVEM ENT IN PLANER-CUTTER SHARPENERS.

Specification forming part of Letters Patent No. 167,920, datedSeptember 21, 1875 application filed May 28, 1875.

7 Be it known that I, GARRY MANVEL, of Rochester, in the county ofMonroe and State of New York, have invented a new and ImprovedPlaner-Outter Grinder, of which the following is a specification:

The invention will first be fully described in connection with drawing,and then pointed out in the claims.

Figure 1 is a sectional elevation of my im-' proved cutter-grinder,taken on the line .1: '00 of Fig. 2. Fig. 2 is a plan view.

Similar letters of reference indicate corre- A is the grindstone, and Bthe cutter to be ground, the cutter being fastened in clamps O, whichare jointed at D to the traversing supports E on'the guide-rest F andthe feedscrew G of a table, along the edge of which the clamps run at Hfor gaging the cutter to the stone, said table being mounted on thevertically-adjustable standards I, which are mounted on the standards J,which are clamped to the sides of the bed-frame K by clamps L, so thatthey can be swung forward or backward at the top to shift the toolforward or backward relatively to the stone to vary the bevel of thetool. The vertical adjustment by the standards I regulates the amount tobe ground 01f. The gageH insures the grinding of the edge straight. Q,is a weighted lever for pressing the cutter on thestone. The weight maybe shifted along to vary the pressure. The lever is connected to atraversing block, N, and rests on a bridge, 0, which rests on theclamps. The standards I are supported and adjusted by the lugs M of thestandards J and the adjusting-nuts P.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The clamps O, jointed at D to the traversingsupports E, combined with a table that supports said clamps at H, andrests upon adjustable standards I J, as and for the purpose described.

2. The combination of weighted lever Q, traversing block N, and bridge0, with the clamps G D, and the traversing supports E, as and for thepurpose specified.
